Subject: [PATCH AUTOSEL 5.4 08/46] media: imx: imx7_mipi_csis: Power off the source when stopping streaming

From: Sasha Levin <[email-masked]>

[ Upstream commit 770cbf89f90b0663499dbb3f03aa81b3322757ec ]

The .s_stream() implementation incorrectly powers on the source when
stopping the stream. Power it off instead.
